[LON-CAPA-announce] New version released - LON-CAPA 2.7.1
Thu, 25 Sep 2008 11:16:43 -0400
New Version 2.7.1 Released
This is primarily a bug fix release for version 2.7.0
It is highly recommended to update 2.7.0 installations with 2.7.1
To use this release you need to have version 1-12 of LONCAPA-prerequisites
If you are upgrading directly from 2.6.3 or earlier, the next
paragraph applies to you:
One of the changes for 2.7 affects scantronformat.tab. After you
have installed 2.7.1 on the primary library server in your domain,
log-in, select the Domain Coordinator role, and go to "Domain
Configuration". Check the box for "Scantron format file", click "Go",
and if you currently use a customized scantronformat.tab file it will
be copied (behind the scenes) from its current location to a new
location where it will be available for selection whenever scantron
grading is used in a course in your domain. Refer to the 2.7.0
release notes -
- for information about changes between 2.6.3 and 2.7.0.
